T 0 all whom it mwy co'ncem Be it known that I, ELBERT W. SHULL, a

' citizen of the United States, residing at Cowley, county of Big Horn, and State, of

Wyoming, have invented certain new and useful Improvements in' Carbon-Producing Apparatus; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to. make and use the same, reference being had to the accompanying drawings, and to the characters of reference marked thereon, which form a part of this specification.

The invention relates to means for obtain- 1ng carbon from natural or other gas, and

the object thereof is to obtain the maximum amount of carbon obtainable by the ordinary burning process from a unit of gas, at the same time makingit possible to use at least a portion of the by-product, heat, for other purposes.

Briefly, the invention comprises hollow, and preferably rectangular, sections mounted for reciprocation against scrapers, through which sections a fluid, suchas air, is passed continuously for the purpose of cooling the sections and thus procurlng a greater carbon deposit from the gas which is being burned against .the under surfaces thereo Thescrapers 'forremoving the carbon from the under sides of the sections are balanced on the sides of the hoppers into which the carbon falls, and scrapers are positioned adj acent these to remove carbon from the sides of the sections.

The sections are arranged in rows laterally and joined together in series longitudinally, each lateral unit being provided w th wheeled carriages to facilitate rec1procat1on of the entire body of units. The ends of the body of units project through and to' the exterior of the building in which the gas is being burned and one end is there connected.

with an air supply, while the other-end has a connection for taking off the heated air by means of which it may be led off for other perspective of one end of the 7 'tion through two hollow sections and shows a joint.,.

F 4 is a rangement.

Fig. 5 is anelevation showing the scraper arrangement; and

Fig, 6 is a' plan thereof. .A framework 10, carrying channel bars 12, supports the operative parts of the deperspective of the scraper arvice. -The framework also supports tracks 13 on which travel the carriages supporting the sections hereinafter described, which are reciprocatedby ineans of the gear 14:, driven by shaft 15 in engagement with a rack 16.

The ends of the rack 16 are connected with angle irons 17, which are bolted or otherwise secured to the hollow sections 18. The

carriages for the hollow sections comprise channel irons 19, secured to the hollow sections and upon the ends of which are mounted wheels 20, by means of cross pieces 21, the wheels traveling on the tracks 13. The ends of the hollow sections are connected by means of flexible tubes 22 with air suppl pipes 23, whereby air may be forced throug the sectlons 18. The rack 16, together with gear 14 and shaft 15, as well as the tubes 22 and the air supply pipes 23, are'positioned between two adjacent buildings, the buildmg llnes being indicated onthe drawings.

Thus the ends of the sections 18 in the opposite buildings, alternately project from the buildings a distance equal to the degree of reciprocation; the carriages and the major portions of the hollow sections are positionedin the buildings in which the gas is burned. At theopposite end of each building the hollow sections are connected by means of a hollow casting 25, having portions fitting into the ends of'the sections 18 and having a hollow piston 26 projecting outwardly therefrom. The iston member 26 telescopes into a cylinder 2 in communication with adischarge pipe 28, provided with a pop-valve 29, adapted to relieve pressure'in case it becomes excessive. The casting 25, as shown, is just outside the building and is adapted to-be reciprocated so that the hollow member 26 .passes entirely into the cylinder 27, as the entire hollow section body within the building is reciprocated. The heated airwhich passes to the pipe 28 may be taken off for any use, such as heating greenhouses.

Gas mains 30 run longitudinally of the buildings and on oppositesides thereof, these mains having connected therewith the feed pipes 31, which supply the burners 32.

ositioned directly below the hollow sections 18 are scrapers 35, adapted to scrape the under faces of said sections 18. The scrapers brackets 36, to which arms 37 arefconnected these arms being provided with looped portions 38, to engageininotches formed in the upper edge of one of the side walls of each hopper into which the carbonfalls' The arms 37 'aresufiicientl long and heavy to slightly overbalance t e scrapers .35, and thereby keep them in contact with the under faces of the sections.

To remove the carbon from the sides of the rectanguar, hollow sections 18, U-shaped scrapers are provided, these having their- .vertical portions slightly concaved as shown,

to present positive scraping edges to said sides. These scrapers 40 are supported onrods 41, which extend'into the ends of the hoppers, the rods passing through the scrapersslightly above their centers. As

shown in Figs. 5 and 6, the ends of adjacent scrapers 35 extend beyond the sides of adjacent sections 7 and therefore beyond the upright portions of the scrapers 40, wherey swinging of the scrapers 40 on the rods 41 is limited, as the hollow. sections 18 I are reciprocated.- It will be noted that both scrapers 35 and scrapers 40 are positioned within the hoppers 50ilwhereby all removed carbon fallsinto said op ers.

The lower portions of t e hoppers 5O dis charge into conveyers 51, driven by bevel gears 52 from a drive shaft 53, these conhand-holes 58.

veyers being adapted to discharge into any suitable receiver.

The detailed construction of the hollow sections is shown in Fig. 3. These sections; are adapted to make a tight joint by means of overlapping parts 55, the sections beingv secured together by means of plates 56, hel

with bolts 57. Adjacent thejoint there is pro perforated at 63 for the passage of bolts by means of which the channel bars 19 of the carriages are secured to the hollow sections.

This operation is also facilitated by the At the middle portion of each hollow section, a hand-hole 65 is provided and is covered with a plate 66 held by bolts 67 Adjacent this hand-hole, osses 68 are provided and apertured to receive bolts for securing the corresponding carriage.

It is to be noted that no carriage is provided at the outer ends of the first and last support this part of the structure. 35 are arranged in pairs 'connected by;

of the hollow sections, where they recipro-.

cate. through the building. This simplifies construction and is satisfactory, since the carriages used 'at the middle of these sections and at the first and last joints will properly In operation, air is blown or drawn I through the pipe 23 into the hollow sections gear 14 and rack 16, the carbon, being de-' posited by burners 32, is scraped from the 'sectionsby scrapers 35 and 40, and falls into .-the hoppers 50, being .conveyed away by conveyers 51. The cooling of the sections pro- 'duces a much greaterdepositof carbon from a unit of gas than is obtainable where I- beams or the like are used for deposit of carbon without being cooled. By the present construction, much, of the heat heretofore radiated from the building is taken out and can be used for other purposes, this being of considerable value in addition to the increased carbon yield.

I claim:

2. In carbon-producing apparatus, the combination with gas burners of hollow. sections mounted thereabove and relatively movable with respect thereto, said sections being arranged side by side, means to pass a cooling medium through each of said sections separately from the others, .and scrapers toengage-and remove carbon from said sections.
